dc.description.abstract	In recent years, the development of new colorimetric and fluorimetric molecular sensors for biologically active metal ions has been extensively investigated because of their potential applications in life sciences, medicine, chemistry, and biotechnology. We report herein the synthesis and characterization of a novel chromo-fluorogenic probe (7) based on N,N-diphenylanilino heterocyclic aldehydes[2] for the selective detection of Cu(II) cation. UV/vis spectroscopic studies of probe (7) in pure acetonitrile in the presence of selected cations (Cu2+, Pb2+, Mg2+, Ge2+, Ca2+, Zn2+, Co2+, Ni2+, Ba2+, Cd2+, Hg2+, Fe3+, In3+, As3+, Al3+, Cr3+, Ga3+, K+, Li+, Na+) were carried out. Of all the cations tested, only Cu(II) is able to induce the appearance of intense absorption bands in the 625 and 1072 nm range with color modulation from faint yellow to deep violet.	por
